Detailed Description

Holds data auth method key, description, and associated shared library file information.

The metadata class is used in a lazy load implementation in QgsAuthMethodRegistry. To save memory, auth methods are only actually loaded via QLibrary calls if they're to be used. (Though they're all iteratively loaded once to get their metadata information, and then unloaded when the QgsAuthMethodRegistry is created.) QgsProviderMetadata supplies enough information to be able to later load the associated shared library object.

Note: not available in Python bindings

Member Function Documentation

◆ createAuthMethod()

QgsAuthMethod * QgsAuthMethodMetadata::createAuthMethod ( ) const

virtual

Class factory to return a pointer to a newly created QgsDataProvider object.

Since: QGIS 3.22

Definition at line 39 of file qgsauthmethodmetadata.cpp.

◆ description()

QString QgsAuthMethodMetadata::description ( ) const

Returns descriptive text for the method.

This is used to provide a descriptive list of available data methods.

Definition at line 29 of file qgsauthmethodmetadata.cpp.

◆ key()

QString QgsAuthMethodMetadata::key ( ) const

Returns the unique key associated with the method.

This key string is used for the associative container in QgsAtuhMethodRegistry

Definition at line 24 of file qgsauthmethodmetadata.cpp.

◆ library()

QString QgsAuthMethodMetadata::library ( ) const

Returns the library file name.

This is used to QLibrary calls to load the method.
